What file types can I upload?

We accept Excel and CSV formats. If your data is in Google Sheets, simply download it as an XLSX file.

Can you handle very large spreadsheets?

Yes. Our processes are designed to handle files with up to several million rows efficiently.

Will you preserve my original data?

Always. We deliver a new, cleaned file and keep the raw source data intact for your records.

What does 'cleaning' include?

It includes deduplication, standardizing formats (like dates or phone numbers), removing invalid characters, and organizing unstructured data.

How long does spreadsheet cleaning take?

Delivery typically occurs within 12 to 24 hours, depending on file size and complexity. Your exact delivery time is shown at checkout.
